Outbreaks of foulbrood in honey bees rearing on Cheju Island(an apiary with 172 colonies) and in Pusan City(an apiary with 100 colonies) were reported in April, 1987. The disease striked on Cheju Island was identified as American foulbrood caused by Bacil

Gumi is surrounded by mountains and Provincial parks are located. A high risk of forest fires that cause the spread of damage effects, and is forecast to have forest fire prevention and Geumohsan Provincial Park to preserve the target Gumi analysis was likely to cause fires. Numerical analysis to the probability of fire, clinical way, even in land cover, using Arc Gis aspect, altitude, slope, watersheds, vegetation, soil characteristics were extracted. Logistic analysis to extract the data in pixels by dividing the number analysis of forest fire risk indices presented in Gumi.

In this paper, we propose an Energy Efficient Media Access Control (EE-MAC) protocol for wireless sensor networks. The proposed scheme is designed to save power consumption and guarantee quality-of-service for real-time traffic. EE-MAC uses the superframe structure which is bounded by the transmission of a beacon frame and can have an active and an inactive portion. The active period is divided into the contention free period (CFP) for real-time traffic transmission and the contention access period (CAP) for non-real-time traffic transmission. We propose the exclusively allocated backoff scheme which assigns a unique backoff time value to each real-time node based on bandwidth allocation and admission control. This scheme can avoid collision between real-time nodes by controlling distributed fashion and take effect a statistical time division multiple access. We also propose the algorithm to change the duty cycle adaptively according to channel utilization of media depending on network traffic load. This algorithm can prolong network lifetime by reducing the amount of energy wasted on idle listening.

According to the Gyeonggi Provincial Office of Education's 2018 Education Statistics, there are 4,692 schools in Korea, and most of them were built before 1985 and the aging of facilities due to earthquake and external environment has reached a serious point and are vulnerable to safety. The Gyeonggi Provincial Office of Education designated 2,561 buildings with floor space of 1,000 square meters or more under the "Special Act on Safety and Maintenance of Facilities (2018.1.18. Full Revision)" and conducted regular safety inspections. The purpose of this study is to analyze the evaluation of school facilities according to the results of a regular safety inspection and to propose a maintenance plan for educational facilities for future defects according to the conditions of the facilities.
